Newline Transfers API is one of 13 APIs that [Fifth Third Bancorp](https://apis.io/providers/fifth-third-bancorp/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Transfers, Payments, ACH, Wire, and Real-Time Payments. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

Initiate, list, retrieve, and cancel Transfers that move assets between Synthetic Accounts across payment rails — ACH, wire, Real-Time Payments (RTP), and internal book transfers. Balance and access checks run before a Transfer is initiated, and Transfers can be canceled only while queued or pending. This is the core money-movement endpoint of the Newline platform.
